  • Studies on the generation of enolate anions from butane-2,3-diacetal protected glycolic acid derivatives and subsequent highly diastereoselective coupling reactions with aldehydes and acid chlorides

    Highly diastereoselective coupling reactions of enolates derived from butane-2,3-diacetal protected glycolic acids 1 and 2 and their alkylated derivatives with aldehydes are reported together with their efficient acid-catalysed deprotection to yield enantiopure anti-2,3-dihydroxyesters. A procedure to provide the corresponding syn-2,3-dihydroxyesters is also described in two cases, proceeding via an acylation–reduction sequence. An usual double addition reaction of butane-2,3-diacetal protected glycolic acid to small aliphatic acid chlorides provides a synthetically useful, densely-functionalised lactone after acidic deprotection.
    报告了来自丁烷-2,3-二缩醛保护的羟基酸1和2及其烷基化衍生物与醛的高立体选择性偶联反应,并且有效的酸催化去保护反应能够生成对映体纯的反-2,3-二羟基酯。同时,在两种情况下也描述了一种提供相应顺-2,3-二羟基酯的程序,该程序通过酰化-还原序列进行。丁烷-2,3-二缩醛保护的羟基酸与小型脂肪酸氯化物的常规双重加成反应在酸去保护后提供了一种合成上有用的、密集功能化的内酯。
  • Catalytic osmylation of electron poor allylic alcohols and ethers.

    日期:1988.1
    The catalytic osmylation of electron-poor allylic ethers and alcohols was studied. In the case of γ-alkoxy E-enoates reaction selectivity was found to range from 2:1 to 8:1 in favor of the arabino (2,3-syn - 3,4-anti) product, regardless of the double bond substitution. Lower (if any) selectivity was found for the Z-isomers. On the contrary, 2-Mthylene-3-hydroxy esters were osmylated with virtually
    研究了贫电子烯丙基醚和醇的催化渗透作用。在γ-烷氧基E-烯酸酯的情况下,发现反应选择性在2:1至8:1的范围内,有利于阿拉伯糖(2,3-syn-3,4-anti)产物,无论双键取代如何。发现Z异构体的选择性较低(如果有的话)。相反,2-甲亚甲基-3-羟基酯几乎完全被2,3-syn选择性地进行了甲磺酰化反应。讨论了影响反应的立体化学结果的因素
  • Highly Diastereoselective Lithium Enolate Aldol Reactions of Butane-2,3-diacetal Desymmetrized Glycolic Acid and Deprotection to Enantiopure <i>anti</i>-2,3-Dihydroxy Esters

    [reaction--see text] The butane-2,3-diacetal (BDA) desymmetrized glycolic acid building block 1 undergoes efficient and highly diastereoselective lithium enolate aldol reactions with both aromatic and aliphatic aldehydes to afford, after an acidic methanolysis deprotection step, the enantiopure anti-2,3-dihydroxy esters in good yield.
